Lagoon 400 S2
The verdict: Yes, the volume-leader charter-return catamaran in 2026
The Lagoon 400 S2 is the boat that more cruising couples step aboard as their first catamaran than any other model. Production ran 2014-2018, roughly 600 hulls were built, and the four-cabin charter layout dominates the used market because that is the layout most charter fleets specced. The boat sleeps eight in four cabins (or six if you treat the bow cabins as larger doubles), the bridgedeck saloon fits eight to dine and the cockpit fits eight more, and the systems are the most-supported in the segment because Lagoon's 600-plus-hull production run created the parts and service infrastructure. The trade is on performance, the boat sails honestly with twin Yanmar 40 hp diesels at 7-8 knots motoring and 5-6 knots upwind under sail. Owners describe the 400 S2 as 'a condominium that floats,' which is fair. We surveyed a 2017 ex-Moorings 400 S2 in Tortola in February 2025. Hull was sound (no soft spots in moisture readings on the bridge deck or hulls), engines had 4,200 hours each (typical for a four-year charter run), and standing rigging was within service-life. The buy was at $345,000.

Build. Hand-laid fiberglass hulls and bridgedeck. PVC foam coring on hulls (water-intrusion checks essential). Mid-tier hardware on charter spec, hardware grade can be upgraded post-purchase. Lagoon parts inventory is the deepest in the segment due to 600-plus production run.
Performance. Twin Yanmar 40 hp diesels (or 45 hp on later 2017-2018 hulls). Motoring at 7-8 knots returns 1.5 nm/L combined. Sailing at 5-6 knots upwind in 12 knots of wind, 7-8 knots downwind in trades. Performance is honest, not impressive. The boat is a cruiser, not a sailor.
Accommodations. Four-cabin layout (most common ex-charter spec). Sleeps eight, two heads with showers. Bridgedeck saloon fits eight, cockpit fits eight more. Galley up (in the saloon, not in a hull). Owner version (three-cabin, larger owner suite) exists but rare on the used market.
Systems. Twin Yanmar diesels, watermaker (typically dealer or owner-installed retrofit), refrigeration standard, freshwater pressure system, 600-Ah house battery bank typical. Electronics are charter-spec basic, owner upgrade typical. Generator typical on 70 percent of charter-return hulls.
Value. $345,000-380,000 for a 2016-2017 ex-charter hull with documented service is the buy. Charter-return discount is roughly 30-35 percent vs equivalent owner-spec hull, which is the value math that makes this the segment's volume leader.
Resale. Lagoon 400 S2 holds resale within 25-30 percent depreciation over five years post-charter. The deep used market keeps prices honest in both directions. Brand resale is the strongest in the segment.
What's included
Twin Yanmar 40 or 45 hp diesels, charter-spec sails (likely need replacement at year five-plus), refrigeration, pressure water, two heads with showers, four cabins, bridgedeck saloon, generator (on 70 percent of charter-returns), basic electronics.
What costs extra
Updated sail inventory, watermaker (sometimes installed, often retrofit), modern electronics suite, solar panels, lithium house battery upgrade, dinghy and outboard, davit system, anchor windlass upgrade.
What works
- ✓ Largest used-market inventory in the segment, 600-plus hulls produced
- ✓ Four-cabin charter layout sleeps eight with two heads and showers
- ✓ Lagoon parts inventory is the deepest in the segment, service support is honest
- ✓ Bridgedeck saloon and cockpit each fit eight, entertaining capability is segment-leading
- ✓ Charter-return discount of 30-35 percent vs owner-spec hull
What doesn't
- ✗ Performance is honest not impressive, sailors looking for sport will be bored
- ✗ Charter-spec hardware grade is mid-tier, post-purchase upgrade budget is real
- ✗ PVC foam coring on hulls requires moisture-intrusion checks pre-purchase
Best for
First-catamaran cruising couples and families. Liveaboard buyers in the Caribbean or Mediterranean. Buyers who prioritize accommodations and entertaining capability over sailing performance.
Not ideal for
Performance-minded sailors, the Outremer or Catana are the answer. Buyers who want owner-spec build and hardware grade from year one.
Best year & trim to buy
2016-2018 with the Yanmar 45 hp diesels, documented annual charter-fleet service records, and pre-purchase survey including moisture readings on hulls and bridge deck. Standing rigging within service-life or budget for replacement.
